Frequently Asked Questions
What fluid types are compatible with the VQ Series Cartridge?
The standard VQ Series Cartridge (no-marking) is compatible with petroleum series oil, emulsification fluid, and water glycol-fluid. The "F3" prefix designation specifies compatibility with phosphate ester fluid.
What is the difference between PC and PCT cartridge marks?
"PC" designates the cartridge kit designed for the shaft end of a single pump or double pump, whereas "PCT" designates the cartridge kit designed specifically for the cover end of a double pump.
How is the rotation of the cartridge determined?
Rotation is determined by viewing the cartridge from the shaft end of the pump. The letter "R" indicates right-hand (clockwise) rotation, while "L" indicates left-hand (counter-clockwise) rotation.
Under what testing conditions is the USgpm flow rate rated?
The USgpm flow rate for the VQ series cartridge is rated at an operating speed of 1200 r/min and a pressure of 0.69 MPa.
What are the rotor inside spline specifications for a 35VQ series cartridge?
The 35VQ series rotor features 37 teeth, a pitch of 40/80, a 45° pressure angle, a major diameter of 24.38 mm, and a minor diameter of 23.10 mm.
How many vanes are typically included in the VQ series cartridge kit?
According to the parts breakdown, the standard VQ series cartridge configuration includes a quantity of 10 vanes in the vane kit.
